ADJUSTABLE ELECTRIC-LIGHT HANGER.

SPECIFICATION forming part of Letters Patent No.483,556, dated October4, 1892. Application led February 5, 1892. Serial No. 420,429. (Nomodel.)

To LZZ whom it may concern/.-

Be 1t known that I, HERBERT L. HOLT, a citizen of the United States,residing at Ellsworth,1

electric lamp and which shall be so constructed as to not only entirelyinclose and conceal the electric Wires, but will also provide meanswhereby the electric lamp can be adjusted in a variety of differentpositions-drawn down,

pushed up out of the way, or moved to the right or left-and will stayrigidly in such' position until it is desired to move the same intoanother position.

With these and many other objects in view, which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination, and arrangement of partshereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure l is a side elevation of myimproved electric-lightarm hanger suspended from the ceiling of a room.Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail inperspective of the ceiling-clamping plate. Fig. 4. is a sectional viewof a pair of the oscillating cupdisks in position for assembling. Fig. 5is a detail sectional view illustrating the sliding connection betweenthe adjusting-disks.

Referring to the accompanying drawings, A represent-s a circularsupporting-plate that is designed to be suitably secured to the ceilingof a room and is provided with a series of depending supporting-lugs B,having inner supporting-shoulders C, which receive the upper annularflange D, of the upper supportingsocket E, one of said lugs B beingremovable, as illustrated in the drawings, so as to allow for theinsertion of the iiange D Within the same and its detachment therefrom.The said supporting-socket E is thus suspended from the depending lugsof said ceiling-plate so that the same may freely turn therein and giveto every movement of the lower supporting devices, and said socket maybe detached i from the ceiling-plate when the device is to be secured toa wall, if so desired.

Pivotally connected to opposite sides of the upper revolublesupportingsocket E are the opposite supporting-arms F, xedly connected ito opposite sides of one of the oscillating adjusting cup-disks G,located olf from or below the said upper socket E. The said cup-disks Gare provided with inner overlapping flanges H, the iiange of one diskworking in the iiange of the opposing disk, and vice versa. The saiddisks are provided with the opposite openings I, which receive theclamping and binding bolt 1, passing therethrough and clamping saiddisks sufiiciently tight so as to cause the same to remain in What-everposition they may be placed. A suitable elastic Washer J maybeinterposed between the head of said bolt and one of said disks to takeoff the strain of said bolts upon said disks. One of the cup-disks G isprovided with atop perforation g, which receives the electric cord orWire passing from the ceiling or Wall through the top inclosing socketE, and the opposite of said disks is provided with a threadedperforation g', which receives the inner end of one of the telescopingtubes H', which receive the electric cord or wire I", passing throughsaid adjusting cup-disks.

The said telescopic tubes H telescope one within the other and may bearranged in any number desired, according. to the length of thesupporting-armrthat may be necessary to be used. As illustrated in thedrawings, the end of the telescopic tube or tubes sliding within thelarger tube is split at M to form a series of spring-tongues, which bitethe larger tube, and therefore serve to hold the telescopic tubes in anyadjusted position, as will be evident; butit will of course beunderstood that the tubes themselves may work suiiiciently tight withineach other, so as to remain fixed in any adjusted position. To the loweror at least outermost of the telescopic tubes H is secured a pair of adj Listing-disks G', similarly constructed to the larger disks, butsmaller than the disks G, inasmuch as only the weight of the electriclamp is carried by said outer disks. The disk G opposite to the onesecured to the outer end of the telescopic tubes is provided with athreaded pro- IOO 'be lengthened or shortened at will.

jectingtubelf, which receives the ordinary electric socket J', whichcarries the ordinary electric lamp K. The electric cord or wire I passesthrough the adjusting cupdisks at each end of the telescopic tubes andthrough said tubes, and is thus connected with and carried to thelamp-socket without being eX- posed to view, while at the same timeevery possible adjustment of the lamp may be had. Now 1t can be readilyseen that the revoluble socket E allows the whole supporting-arm to b eturned in any direction that may be desiredwwhjle by the use of theadjusting cup- M/disks the telescopic lamp-arm may be set and turned atany angle desired, and also the lamp itself, according to the needs ofthe user, while at the same time the whole device may When shortened,the electric cord or wire I is forced backr into the larger cup-disks Gand is drawn out from the same when the light-arm is lengthened.

In order to prevent the entire withdrawal lof the telescopic sections'oftubes one from the other, those receiving and accommodating othersections are provided with anged screwcaps .I at their lower ends,having bottom openings exactly registering with the tube sliding thereinand through which the springtongues of such tube will not pass.

Having thus described my invention, what I claim, and desire to secureby Letters Patont, is-

1. In an electric-light hanger, the combination of a revoluble socket,adj usting-disks, one of which is pivotally suspended from said socket,and telescopic tubes connected with the other of said disks and adaptedto support the electric lamp and inclose the electric cords passingthrough said socket and adjusting-disks, substantially as set forth.

2. In an electric-light hanger, the combination of a supporting-socket,adjusting-disks, one of which is pivotally suspended from said socketand receiving and accommodating the electric cord therefrom, andtelescopic lampsupporting tubes connected with the other of said disksand receiving and inclosing the electric cords passing therethrough,substantially as set forth.

3. In an electriclight hanger, the combina tion, with a supporting-platehaving a series of depending shouldered lugs, of a revoluble flangedsocket resting and working upon said shouldered lugs, adj usting-disks,one of which is pivotally suspended from said socket and receiving theelectric cord, and telescopic lamp-carryin g tubes connected with theother Y 'the electric lamp, substantially as set forth.

5. In an electric-lightk hanger, the combinau tion of asupporting-socket, hollow cup-shaped disks having overlapping flanges, aclampingbolt clamping said disks adj ustably together, supporting -linkspivotally connected with said socket and Xedly to one of said disks,

telescopic supporting-tubes connected with the other of said adjustabledisks, and similar hollow cup-shaped disks secured to the outermost ofsaid telescopic tubes and adjustably carrying the lamp, the electriccord passing through said socket, the opposite adjustingdisks, andintermediate telescopic tubes to the lamp, substantially as set forth.

6. In an electric-light hanger, the combination of asupporting-socket,hollow cup-shaped disks working adjacent to saidsocket and provided with overlapping flanges, a clamping-bolt adjustablyclamping said disks together, elastic washers interposed between thehead of said bolt and said disks, supporting-arms pivotally connectedwith said socket and fixedly to one of said disks, telescopicsupporting-tubes, one of which is connected at one end to the other ofsaid disks, and similar hollow cup-shaped disks, one of which receivesone end of one of said telescopic tubes and adj ustably carrying thelamp, the electric cord passing through said socket and entirelyinclosed by the opposite adjusting-disks and the intermediateadjusting-tubes, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aiiixedmy signature in the presence of two witnesses.
